The maximum compressive stress a material is capable of developing. With a brittle material that fails in compression by fracturing, the compressive strength has a definite value. In the case of ductile, malleable, or semiviscous materials (which do not f ...

The current flowing to or from a unit area of an electrode surface, generally expressed as amps per sq ft or milliamperes per sq ft (also milliamps per sq cm, etc).

Removing the thick layer of oxides formed on some metals at elevated temperatures.

The electroplating of zinc upon iron or steels

The range of the stress-intensity factor during a fatigue cycle.

A metastable lamellar aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures above the bainite range.

An instrument for indicating or measuring a small electric current by means of a mechanical motion derived from electromagnetic or electrodynamic forces produced by the current.

The potential corresponding to the maximum active current density (critical anodic current density) of an electrode that exhibits active-passive corrosion behavior.

A pair of dissimilar conductors, commonly metals, in electrical contact. See also galvanic corrosion.

The mass of unit volume of a material at a specified temperature.

Heating a metal or alloy to such a high temperature that its properties are impaired. When the original properties cannot be restored by further heat treating, by mechanical working, or by a combination of working and heat treating, the overheating is kno ...

Foreign substance which comes from the environment, adhering to a surface of a material

Electrodepositing a metal or alloy in an adherent form on an object serving as a cathode.

The number of cycles of stress that can be sustained prior to failure under a stated test condition.

An imprecise term used to denote a treatment given cold-worked material to reduce its strength to a controlled level or to effect stress relief. To be meaningful, the type of material, the degree of cold work, and the time-temperature schedule must be sta ...

A composite metal containing, two or more layers that have been bonded together. The bonding may have been accomplished by co-rolling, co-extrusion, welding, diffusion bonding, casting, heavy chemical deposition, heavy electroplating, or explosive claddin ...

Loss of carbon from the surface layer of a carbon-containing alloy due to reaction with one or more chemical substances in a medium that contacts the surface. See also dealloying.

A process involving conjoint corrosion and cavitation.

Electrochemical system consisting of an anode and a cathode immersed in an electrolyte. The anode and cathode may be separate metals or dissimilar areas on the same metal. The cell includes the external circuit, which permits the flow of electrons from th ...

An accelerated corrosion test for some electrodeposits for anodic coatings on aluminum.
